What is the source of the question. I think the question is itself incomplete because whenever an incoming packet arrives at the router, then the router performs the Logical AND operation between the subnet mask and the destination address provided in the IP header of the packet, the result of the AND operation is subnet id provided that the network uses the SUBNET Technology. And every interface has its own subnet id associated with the interface (which is missing in the question) based on the subnet mask only we can't decide where this packet will be forwarded.

If the subnet ID associated with the interface B is $200.200.200.128$ then option (A) is correct. And if the subnet ID associated with the interface B is $200.200.200.192$ then option (B) is the correct answer.

As per the subnet mask, not ID provided in the question to the two bits are for subnet and 6 bits are for host.

@Jason , can you plz explain what do we mean when we say we have a subnet mask associated with an interface , we have an interface between two networks and subnet mask is associated with a network so how come we are saying that an interface has a subnet mask , plz explain this precisely .
